Influence of active flux to butt weld and T type penetration weld of TA15 titanium alloy TIG weld

Penetration welding is an important welding type in titanium thin sheet structures.Based on the analysis about welding parameter,weld shape,porosity,weld microstructure,tensile property、bending property,and gas amount,the influence of the A-TIG technique on penetration welding joint of the TA15 titanium alloy was investigated,also the contrast between penetration weld and butt weld was investigated.The results show that the A-TIG technique could make the similar influence on such respects as welding parameter,weld shape,porosity,weld microstructure,and gas amount to the both penetration weld and butt weld,also the similar influences of A-TIG on the tensile property、bending property to the penetration welding and the butt weld.
